A Massive Summer of Growth for ENGIE

French energy major ENGIE has significantly accelerated its battery energy storage system (BESS) deployment across Europe. In July and August 2026 alone, the company added 1.1 GW and 3.3 GWh of battery storage capacity across seven European countries. This aggressive summer expansion has propelled ENGIE's total storage capacity in Europe to 4.7 GW, encompassing both operational assets and projects currently under construction, solidifying its position as a leading player in the continental energy transition.

Strategic Acquisitions and Developments Across the EU

ENGIE’s growth strategy involves a mix of greenfield developments and strategic acquisitions across key EU member states. In Poland, the company built a massive 758 MW and 2,156 MWh portfolio. This includes the acquisition and expansion of the Tursko Wielkie asset to 320 MW and 1,280 MWh, alongside a new 438 MW project in the Łódź region, with commissioning scheduled for 2028-2029. These large-scale deployments are critical for integrating Poland's growing renewable capacity.

ENGIE's diverse portfolio highlights a comprehensive approach to the European energy transition, balancing standalone utility-scale BESS with co-located renewable integrations to maximize asset value and grid stability.

Regional Footprint from Iberia to the Baltics

Beyond Poland, ENGIE is making significant strides in other EU markets. In Romania, the company acquired a ready-to-build 54 MW project in Călan and has 85 MW currently under construction. In Spain, ENGIE secured a 66 MW asset in Tarifa. Belgium sees the start of construction on a 74 MW system at Coo, complementing existing pumped-storage infrastructure. Meanwhile, in Portugal, ENGIE is building two 10 MW co-located systems with wind farms, and in the Netherlands, it inaugurated the 35 MW BESS Maxima in Lelystad, its largest operational Dutch battery to date, complementing local solar and thermal assets.
